Product details
Overview
DMC3730UVT from Diodes Incorporated is a complementary pair enhancement-mode MOSFET in a single TSOT26 package, integrating an N-channel (25V, 0.45Ω @ 4.5V) and P-channel (–25V, 1.1Ω @ –4.5V) device for bidirectional power control. It delivers 0.68A/–0.46A continuous drain current at 25°C, features ESD-protected gates, and targets space-constrained DC-DC converters requiring low RDS(ON) and fast switching.
For engineers reviewing the DMC3730UVT datasheet, DMC3730UVT pinout, DMC3730UVT application, or DMC3730UVT equivalent, key selection criteria include gate threshold voltage matching (±0.7V typ), thermal resistance (140°C/W at 2oz copper), body diode conduction capability, and AEC-Q101 qualification for automotive-grade reliability.
Technical Context
This dual MOSFET implements complementary switching in half-bridge or load-switch configurations, with independent gate control enabling synchronous rectification or high-side/low-side drive. Its low input capacitance (Ciss = 50pF/63pF) and fast turn-on delay (3ns/7ns) support >1MHz operation in compact power stages.
The integrated N+P pair shares thermal coupling in a monolithic TSOT26 footprint, allowing matched temperature tracking and reduced PCB layout complexity versus discrete solutions. Gate protection diodes on both channels suppress transient overvoltage during commutation, supporting robust operation in noisy environments.

Equivalent & Alternatives
The following parts are listed as comparable options for similar complementary MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DMC2038LVT-7 | Lower RDS(ON) (0.28Ω/0.65Ω), higher Qg (2.2nC/1.4nC), same TSOT26 | Better efficiency above 0.3A but slower switching; less suitable for >1MHz designs | Choose for thermally limited 3.3V systems where conduction loss dominates |
| SI3483DV-T1-GE3 | Higher VDSS (±30V), larger RDS(ON) (0.65Ω/1.5Ω), SO-8 package | Supports 24V industrial rails but requires 3× PCB area; no AEC-Q101 rating | Choose only when 30V margin or legacy SO-8 footprint is mandatory |
Compared with DMC2038LVT-7 and SI3483DV-T1-GE3, the DMC3730UVT balances gate drive simplicity (1.8V logic compatibility), thermal efficiency (140°C/W), and automotive qualification-making it optimal for space-constrained, battery-powered, and AEC-compliant designs where switching frequency exceeds 500kHz.

FAQ
What is the maximum junction temperature for continuous operation?
The DMC3730UVT supports continuous operation up to +175°C junction temperature, verified per AEC-Q101 stress testing. Derating begins at +150°C ambient when mounted on 2oz copper; thermal design must maintain TJ ≤ 150°C under worst-case load and airflow conditions.
Can the N-channel and P-channel be used simultaneously in a half-bridge configuration?
No-the DMC3730UVT lacks internal bootstrap or level-shift circuitry required for true half-bridge operation. It supports complementary switching only in load-switch or synchronous buck topologies where gates are independently driven with referenced supplies.
Is the TSOT26 package compatible with standard reflow profiles?
Yes-the TSOT26 package is qualified for JEDEC J-STD-020 Class 1 moisture sensitivity and supports peak reflow temperatures up to 260°C. Recommended profile uses ramp rate ≤3°C/s, soak at 150–200°C for 60–120s, and peak at 245±5°C for ≤30s.
Does the device include internal gate resistors?
No-DMC3730UVT has no integrated gate resistors. External series gate resistors (typically 5–10Ω) are required to damp ringing and control dV/dt during switching, especially when driving inductive loads or operating above 500kHz.
